ZIM Project "Wood E-Bike" in cooperation with System 180 GmbH

Prof. Pfriem's working group and the innovative Berlin-based company System 180 GmbH have set themselves the goal of drastically reducing the carbon footprint of a bicycle by the beginning of 2015 by replacing its metal wherever possible with the natural material wood. At the same time, mobility is to be increased by means of electric motor assistance. In short, the first production-ready wooden pedelec is to be launched on the market. The frame and also the replaceable fork are made of ash slats. First glued into shape, the individual parts are completely machined on the CNC machine. Battery, control unit and the entire cabling can thus be optimally integrated into the frame, so that only the voluminous body of the bike gives an indication of the hidden pedal assistance.
The design also led to it being nominated by the IF- Design Award in Munich in February 2014 and exhibited at the Holz-Handwerk trade fair in Nuremberg from March 26 to 29 (Hall 10.1 Booth 104 - Kleiberit booth). It was also on display at the Hannover Messe from April 7 to 11, 2014 (Hall 2, Booth C31). From May 11 to 15, it can be viewed at the LIGNA in Hanover in Hall 26, Booth B65 at the Kleiberit booth.
We at the HNE were able to bring the project a good deal closer to its goal in many technical details through tests on materials and adhesives, development of process engineering solutions and through the numerous results obtained on new testing machines. The University of Hamburg and the associated ThÃ¼nen Institute have also been won over for cooperation in order to validate measurement results.
Of course, there is ongoing student support, whether in the form of bachelor theses, engineering projects or as student assistants.
